 Jul 8 asked Finding points of intersection between a line and a curve May 8 awarded Caucus Apr 10 accepted How can I determine the values of a third point to make all 3 collinear in $\mathbb{R}^3$ Apr 10 comment How can I determine the values of a third point to make all 3 collinear in $\mathbb{R}^3$ Thanks, I did add the point and was checking it but with no clue what I was doing, but I can figure out why it works soon thanks to your explanation and example. Thank you! Apr 10 comment How can I determine the values of a third point to make all 3 collinear in $\mathbb{R}^3$ I think this is a good answer, but I am lacking so much basic knowledge that it is hard to understand exactly what I am doing. My instinct tells me based on what you say that $3 + t(-2) = 2$ so $t = 1/2$ and $(1/2, 1, -1)$ satisfies the equation?

Apr 7 comment What does it mean to be proportional to something? Hm that is interesting, and it confirms my answer when I use the k, that really helps too. It is truly discomforting that my brain does all that without informing me how it was done.. Many thanks! Apr 7 asked What does it mean to be proportional to something? Apr 6 accepted Find all values of $a$ such that $w = ai- \frac{a}{3}j$ is a unit vector Apr 6 comment Find all values of $a$ such that $w = ai- \frac{a}{3}j$ is a unit vector Thanks a lot, that problem has been bothering me but no longer! Apr 6 awarded Critic Apr 6 comment Find all values of $a$ such that $w = ai- \frac{a}{3}j$ is a unit vector So that would lead me to $a = +\sqrt{\frac{9}{10}}$ and $a = -\sqrt{\frac{9}{10}}$. Does that sound correct?

Mar 12 comment How might one go about proving this poorly worded theorem about divisibility with the number 3? The contrast in the clarity between my claim and your theorem is palpable, well done sir.
